R4 CANBus tutorial failures

[jlit]

Referencing docs at https://docs.arduino.cc/tutorials/uno-r4-minima/can from @karlsoderby

See comments in https://forum.arduino.cc/t/using-can-with-minima-r4/1162333/4.

Three different people have reproduced inability to use Arduino_CAN with R4 and SN65HVD230 CAN Board Accessory Network Transceiver modules. Looking for a good working example or help with the library. Thank you.

Hi @jlit , sorry to see that you are having issues.

I saw that in the forum thread you got some support from the library author and that you managed to get something working. We will investigate a bit more on why there's issues with communication between the Minima and a different boards, and to update the documentation.
